Managing resources effectively is a critical but often underestimated aspect of Public Key Infrastructure (PKI). While the focus is typically on the technical implementation, the long-term success and trustworthiness of a PKI system depend heavily on sourcing the right resources—financial, computing, human, and management. This presentation delves into the complexities of resource management in PKI, explaining how careful planning, monitoring, and alignment with organizational strategy can strengthen infrastructure and enhance trust over time. We will also explore current and future trends in resource sourcing, shedding light on how organizations can adapt to evolving challenges.
